Specification of Letters Patent.

Patented Jan. 27, 1914.

Application filed May 14, 1913. Serial No. 767,601.

To aZZ whom it may concern:

Be it known that I, DANIEL M. HARRISON, a citizen of the United States, residing at Dyer, in the county of Crawford and State of Arkansas, have invented new and useful Improvements in lVindow-Shade Rollers, of which the following is a specification.

The invention relates to brackets, and more particularly to the class of window shade brackets.

The primary object of the invention is the provision of a window shade bracket wherein a spring is held in contradistinction to the mounting thereof in the shade roller as usual, so that the said roller is rendered strong and more durable and the shade will be automatically rewound thereon when unwound therefrom to permit the adjustment of the shade in the ordinary well-known manner.

Another object of the invention is the provision of a bracket of this character wherein the spring for the rewinding of the shade on its roller is concealed from view in said bracket, the bracket being made from metal so that it can be easily manufactured and at a minimum expense.

A further object of the invention is the provision of a bracket wherein the shade 'can be readily adjusted on its roller, and which is simple in construction and thoroughly reliable and eiiicient in its working.

lVith these and other objects in view, the invention consists in the construction, combination and arrangement of parts as will be hereinafter fully described, illustrated in the accompanying drawing, and pointed out in the claim hereunto appended.

In the drawing :Figure 1 is a front elevation of a window shade, showing the same mounted in the brackets constructed in accordance with the invention. Fig. 2 is a sectional view on the line 22 of Fig. 1. Fig. 3 is a transverse sectional view on the line 3-3 of Fig. 2. Fig. 1 is an end elevation of the shade roller. Fig. 5 is a side elevation of one of the brackets.

Similar reference characters indicate corresponding parts throughout the several views in the drawing.

Referring to the drawing in detail, 5 designates a window shade which is connected to and supported by the shade roller 6, the same being journaled in a pair of brackets A and B respectively, which are fastened as usual to the window casement.

The bracket A comprises a base 7 through which are passed fasteners 8, such as screws, for the securing of the same to the window casement, and integrally formed with this base 7 is a circular-shaped casing 9 provided with flat side cheeks 10 formed with central alining openings 11 in which is journaled a stud axle 12 formed with a medial enlarged portion 13 which is of a length corresponding to the space between the cheeks 10 of the casing and works against the same so as to prevent the displacement of the axle 12 in the said casing.

Fixed to the axle 12 is one end of a coiled tensioning spring 1 1 which surrounds the said axle and has its opposite ends fixed to the casing 9 so that on the turning of the axle in one direction the spring is caused to wind about the same for the tensioning of the shade roller 6 so that the window shade 5 will be wound thereon for the adjustment of the same, the spring 14 being wound when the shade roller is pulled upon for the unrolling thereof from the roller.

Surrounding one end of the axle 12 exteriorly of the casing 9 and integrally formed with one of its checks is a notched hub 15, the notch 16 therein being engaged by either of a pair of dogs pivoted at 18 to the end of the roller 6 adjacent to the hub, the dogs being disposed diametrically opposite each other and gravitate toward the center or axis of the roller 6 for engagement with the hub to lock the roller against rotation. The end of the axle 12 surrounded by the hub 15 is provided with a rectangular shaped socket 19 in which is detachably received a correspondingly shaped pintle 20 fixed to the roller at one end thereof. while at the opposite end of the latter is fixed a circular pintle 21, the same being fitted in a correspondingly shaped opening 22 formed in the bracket B, which is secured to the window casement in a like manner as the bracket A, the brackets A and B being of similar shape and design.

The window shade can be adjusted in the ordinary well-known manner, and on the unwinding thereof from its roller the spring 1 1 is tensioned so as to rewind the shade automatically when it is released, it being understood of course that the roller will be locked against rotation for holding the shade extended or unwound from the roller to the desired extent.

From the foregoing it is thought that the construction and manner of operation of the device W111 be clearly understood, and therefore a more extended explanatlon has been omitted.

": ranged Within the casing and having reduced ends journaled in the said opening, one of said reduced ends being provided with a socket, a hub fixed to the casing at one side thereof concentrically to one reduced end of the stud and having a notch adapted to be engagedby the pawls on a.

Window shade roller, and a coiled tension spring Wound about the said stud axle and having one end fixed to the casing and its opposite end fixed to said stud axle.

In testimony whereof I affix my signature in presence of two Witnesses.

DANIEL M. HARRISON. Witnesses:

ANNIE DYER, Mrs. ADELINE HARRISON.
